Warped debris disks around stars are blowin' in the wind

A team led by John Debes at NASA's Goddard Space Flight Center finds that a star's motion through interstellar gas can account for warped debris disks around stars. The fine dust particles are affected by the drag force from the gas, causing them to change their trajectory and creating unusual shapes.
